Un problème de nappe phréatique<br />

The problem is, find p and Ω such that :<br />

⎧<br />

⎪⎨<br />

⎪⎩<br />

−∆p = 0 in Ω<br />

p<br />

∂p<br />

∂n<br />

= y on Γb = 0 on Γd ∪ Γa<br />

∂p<br />

= q<br />

K nx on Γ f (Neumann)<br />

∂n<br />

p = y on Γf (Dirichl<strong>et</strong>)<br />

where the input water flux is q = 0.02, and K = 0.5. The velocity u of the<br />

water is given by u = −∇p.<br />
